Network Timing
摘要
Network timingNetwork timing (hereinafter shortly referred as SyncNet) is a network method of slips overcoming which is based on the maintaining high accuracy and stability in the network. Essentially, it is a forced method of maintaining a roughly equal mean frequency with a limited phase offset (N. Biriukov, N. Triska Time and synchronization in telecoms. – Lecture Notes in Electrical Engineering. Volume 560: Advances in Information and Communication Technologies. Processing and Control in Information and Communication Systems. – Springer, 2019. ISSN 1876–1100. ISBN 978–3-030–16,770-7.- p. 205–223.). SyncNetSyncNet is widely used both in legacy TDM-based networks and in modern packet-based networks. The chapter describes network timing issues in the different stages – from planning to maintenance and conformity assessment. The presented guidelines, examples and case studies are mainly based on the “classic” SyncNet solutions designed for legacy TDM-based networks. Being well standardized and worked out in practice, these solutions do not lose relevance today, serving as a basis for developing timing solutions for new generation carrier-class packet networks.
